Aquaponics is a system for farming fish and plants together in a mutually beneficial cycle. Fish produce waste that is a fertilizer for plants while plants suck up the nutrients as they purify the water. The system is efficient and environmentally friendly. A farm in Norwood, NC is pioneering the technique.

With new understanding about the structures of human organs, scientists are growing miniature human livers, hearts and kidneys and linking them together with a blood substitute, to evaluate the effects of new drugs. Watch the video and then go through the interactive PowerPoint presentation below!

Next door to A2 Wind Tunnel, where cyclists work on reducing their wind resistance like in this video, is a larger building, another wind tunnel. But this facility, called the AeroDyn Wind Tunnel, is not meant for bicycles. It is meant to test cars, either for NASCAR, land speed competitions or drag races. Several NASCAR racers, including Dale Earnhardt Jr. have brought their cars to this tunnel.

Coal ash is a byproduct of burning coal to generate electricity and is often stored in ponds near power plants. But when coal ash spilled out of a Duke Energy storage pond into the Dan River, it focused attention on the problem of storing coal ash. While some is currently used in concrete, NC A&T Researchers are finding a new use for coal ash as a super strong building material.

Blueberries are nature's super fruit, packed with fiber, antioxidants and vitamins. Blueberries are also a big industry for North Carolina. Now scientists are working to decode the blueberry genome and create the super blueberry bush, which would help the state's blueberry industry.

Wake Forest University scientists pioneer using drone aircraft for ecological monitoring. They're flying drones over the Amazon rainforest to study the tree canopy and the amount of carbon dioxide the forest releases.

Biomedical engineers at Duke University have been able to grow living skeletal muscles in the lab that look and act like the real thing. It's a first step in growing human muscle that can treat injuries and disease.
